the world's lamest jedi mind trick: aw c'mon

What the hell just happened there? How is the phrase "aw c'mon" in any way persuasive? What does it mean? What compelling logic does it represent?

And, yet, mysteriously .... it works.

Jedi mind tricks are reported to work on the weak minded. So any time anybody tries any jedi mind trick (logical fallacy) isn't that the same as openly calling somebody stupid? And if the jedi mind trick is the cheapest and weakest of the bunch, isn't that somehow calling somebody not just stupid, but REALLY stupid?
